P2.4 GPIO2 I/O Functions as a GPIO, corresponding to the PA5 pin of the internal IC.
TP1 nRST I Hardware reset pin, and the chip is reset when the level is low. TYZS9V has a power-on reset function, and this pin is not necessary in the actual situation.
TP2 ADC AI ADC port(1),12-bit precision SAR analog-to-digital converter.
TP3 SWCLK I/O JLINK SWCLK programming pin, which can also be used as a GPIO in normal programs.

Note: P indicates power-supply pins, I/O indicates input/output pins, and AI indicates analog input pins. nRST is only a module hardware reset pin, which cannot clear the ZigBee network configuration. (1): This pin can only be used as an ADC interface and cannot be used as a common I/O pin. If this pin is not used, it must be disconnected. When this pin is used as the ADC input interface, the input voltage range must be 0 to AVDD, which can be configured using software.

5. Antenna Information

5.1 Antenna Types

By default, the onboard PCB antenna is used. The antenna gain is about 2.0 dBi.

5.2 Antenna Interference Reduction

When you use an onboard PCB antenna on a ZigBee module, make sure that the antenna on the module is at least 15 mm away from other metal parts to ensure optimal wireless performance. It is recommended that the antenna location on the PCB be hollowed out. To prevent negative effect on antenna radiation performance, do not route copper or cable wires along the antenna area of the user PCB board.

6.3 Production Instructions

Storage conditions of a delivered module are as follows:

  1. The anti-moisture bag must be placed in an environment where the temperature is under 30°C and the relative humidity is under 85%.
  2. The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed. Precautions:
  3. Throughout the production process, each involved operator must wear an electrostatic ring and electrostatic clothes.
  4. During the operation, strictly protect the module from water and strains.
